For general hardware hacking I'd get a pirate bus ($30), and a saelae logic clone (cheap). Maybe a nice cheap oscilloscope (but they go for $300+), but logic clone can get you mostly there.
hantek handheld for 190.
At worst if you wanna try it out without spending so much money you can try out the bus pirate from dangerous prototypes it’s only ~27.
It's great for beginners as it has a huge and friendly community behind it and you can easily work your way up from beginner to more intermediate/advanced.
Next it's fun to mess with the screens at the pub.
Somewhere along the way, realizing that someone out there has the remote you lost long ago and all you really want is an on/off button and now you can get one.
For me so far it's a universal remote with a kind of weird interface.
